Install XCode from the Mac App Store
Install the XCode command line tools:
1. Open Terminal
2. Type this command and hit enter: xcode-select --install

Install a fortran compiler:
1. Go to www.hpc.sourceforge.net
2. Download the latest version of GCC. File should be: gcc-9.2-bin.tar.gz
3. Open terminal
4. Go to directory where file was just downloaded. (e.g.: cd /Downloads)
5. Unzip the file (may not be necessary). Type: gunzip gcc-8.1-bin.tar.gz
6. Install GCC. Type: sudo tar -xvf gcc-8.1-bin.tar -C /   (it will ask you for your computer’s password)
7. To check if it installed properly you can type: gfortran -v
    If GCC installed correctly then you shouldn’t get an error.
